So I got a copy of the beta of Windows 7 and installed it on my desktop computer at home on a separate drive.  I still have Vista x64 installed and decided to do a separate install of Windows 7 based on previous experiences with Microsoft Betas.  I must say that the install went very well and so far I have only found a few things that do not install on Windows 7 that I can install on Vista.  One of them that does not run is Virtual Clone Drive, my ISO loader.  So I had to switch to PowerISO to load a few items that I store in ISO format. 

I am extremely pleased at the memory footprint.  I am seeing ~800 MB of RAM being used as opposed to Vista, which on my machine is hovering about 1.7 GB of ram with nothing else running.

 The biggest issue that I have with Windows 7 right now is that I am getting an odd reporting from the Windows Experience Index.  On Vista, the Windows Experience Index looks like this

 

vistawei

 

but, on Windows 7 with the same hardware it reports:

 

w7ei

 

I am a bit concerned about the new disk data transfer rate rating as show in Windows 7 and am trying to figure out if this issue is related to the beta of Windows 7 or what is going on.

In the Things to Know About This Beta Release of Windows 7 document (http://download.microsoft.com/download/F/D/B/FDBFC5A5-51CD-4C8D-9F18-7BCC3810498E/Windows%207%20Beta%20Things%20to%20Know.htm) it states that they changes some of the experience index calculations:

"The method of calculating the Windows Experience Index (WEI) has been updated to reflect newer hardware. The potential maximum value is higher (7.9). Also new tests, such as for disk latency, may result in lower scores for some systems.

No action is required, although firmware updates may be available for your devices which could improve the WEI value."

This might explain your lower disk score.

It does seem to me that my HITACHI Deskstar 7K1000 HDS721010KLA330 (0A35155) 1TB 7200 RPM 32MB Cache SATA 3.0Gb/s Hard Drive should not rate as a 3.0 under any circumstances as I just bought this drive. At first I thought it was that I was using a generic SATA driver, but I have ensured that I am using the correct driver (or at least the Vista one).
The system still performs well, I think it is somewhat a nagging issue that the same HD is just "slower" in Windows 7.

Here's my experience:

Seems to be an issue with SATA drives. From another post of mine:

Same thing here. Athlon 64 X2 5200+, 8GB RAM, 2 SATA hard drives, nForce 4 Ultra chipset (Abit KN9-Ultra), Radeon HD3650 512MB PCIe video card. Disk score in Vista was 5.7, now it's 3.0. Processor score actually went up from 5.2 to 5.7?

That disk score though is somewhat disconcerting, but I fear all too real. In a dual boot setup with Vista x86 and Windows 7 64-bit, I used Nero vision to create a DVD from an .avi file. The video was 1:22 (hr:min). In Windows 7 it was well over an hour, and I was just over half done. Switched to the Vista install and it completed in just over 45 minutes. Clearly there are other variables here, one obvious one is that Win7 was using Nero 8 and Vista using Nero 9. Also, the 64-bit Win 7 vs. 32-bit Vista (both Ultimate). I could clearly see the video in the window as it was being encoded was somewhat "jerky" in Windows 7. Given the size of the files and the disk usage during encoding, it leads me to believe that the lower disk score reflects a very real underlying issue.

Graphics scores were also down, but only by .6 and .5, and I attribute that to driver issues. The ATI Beta driver that Windows Update recommended left me with an ugly situation where my Samsung LCD was not recognized and the display adapter in Device Manager had the lovely yellow exclamation point. I had to uninstall and manually install the Catalyst 8.12 drivers to restore things to normal.

UPDATE: It seems to be an issue with SATA disks. I've seen a few rumblings around with folks having similar issues with SATA drives. Strangely, my test work PC, which is only a single core Athlon 64 3400+, with 3GB RAM, and an older single 80GB IDE disk, which scored a 5.4 on the WEI for the Primary Disk.

nope it's not SATA drives only.. I have an ATA-133 drive and my score dropped from 5.0 in Vista to 3.0 in Windows 7 - I'm convinced there is a problem with the code.

Otherwise I'm loving W7 - just hope it doesn't get bloated like Vista is before the release. I'm not a Vista hater at all but it is resource intensive.. I can't believe how much disk space gets consumed on the system partition under Vista.
